APPARATUS FOR RECORDING MORSE TELEGRAPHIC CHARACTERS.

SPECIFICATION forming part of Letters Patent No. 647,729, dated. April 17, 1900.

Application filed November 13, 1899. Serial No. 736,857. (No model.)

T0 if/ZZ whom, t may concern:

Be it known that we, CHARLES STEVENS, CHARLES CLEMENT VYLE, and WILLIAM MIL- NER, subjects of the Queen of Great Britain, residing at London, England, have invented certain new and useful Improvements in Apparatus for Recording` Morse Telegraphic Characters, of which the following is a full, clear, and exact description, and for which we have made application for British Letters Patent, .dated February 3, 1899, upon which application no patent has been granted.

The object of the present invention is to provide an instrument which will produce a tape having perforations representing visually dots and dashes of the Morse code, `so that it may be read by sight, or it may be passed through a repeater and the message read up by sound, and when desired it may be used for retransmitting a message.

The invention `is illustrated in the accompanying drawings, in which- Y Figure l is an elevation of Va receiving instrument. Fig. 2 is a plan', and Fig. 3 is a sectional elevation, of parts of the same.

Referring to the drawings, A is the framing of the instrument, which is situated on a wooden table B, having drawers C and D.

a is aconstantly-working plunger or pusher working in guides a and pivoted at a2 to a connecting-piece or eccentric-strap a3, operated by the eccentric h,mounted on the shaft b'. This shaft b is driven, preferably, by means of a small electromotor M, giving motion to the toothed wheel e, which rotates the pinion b2, ixed on the eccentric-shaft b. The plunger -or pusher a has a foot piece a4 to act on the punch c.

'c is a punch mounted in guides c7 and formed with a fine end or cutter c2 for perforating the strip d,of suitable material, preferably paper, which latter is fed forward regularly by a short train of wheels driven by the wheel e.

The punch c is provided with a tensionspring c3. The strip of paper ol is drawn off the roll d in the drawer D and passes over guide-pulleys cl2 cl3 and under a tension-pin d4 to the punching table or die f, having a hole f therein, through which pass the pieces of paper cut by the cutter c2. These pieces fall into the drawer C. The strip of paper passes from the punching-table f under a tension-pin d5, around guide-pulleys d6 037 to the draw-off roller e', driven by the train of gearing before mentioned.

The punch c has a slot c4 in its side, within which the pusher-'foot a4 works. This slot is equal in length to the movement of the plunger orpusher a.

The line-coils g (shown in dotted lines, Fig. 1 and in detail, Figs. 2 and 3) are wound to a resistance of one hundred plus one hundred, with pole-pieces g', armatures g2, and limited stops g:s similar in-construction to that of an ordinary receiver, with the difference that a forked lever h, projecting over a small bolt il and having its fork h engaged by a pin 1I', attached to said bolt e', is substituted for the usual arm carrying the marking-disk. The bolt t' passes through a hole in the punch c, at one end of the slot c4 therein.

From the above description it will be seen that immediately a marking current flows through the line-coils g the forked lever h moves from right to left, pushing the bolt 't' through the hole in the punch c and underneath the foot a4 of the constantly-working plunger or pusher ct, thus shortening the length of the slot c4 in the side of the punch c, the result being that the point or cutter o2 is forced through and withdrawn from the paper strip d at a great speed, and as the paper strip (Z is being drawn forward at a constant speed a slot is cut therein representing a dot or a dash, according to the time that the marking-current is caused to iiow through the line-coils g. A reversal of the current to spacing moves the fork from left to right, withdrawing the bolt t' from underneath the foot a4 of the plunger a, in which position the plunger ceases to act on the punch e. With the plunger working upv and down at a rapid rate and the small sliding bolt t' for altering the length of the slot in the side of the punch c under the control of the marking and spacing currents, Morse characters, as shown in Fig. et, can be punched at the end of a line with the usual working currents. The motor-battery is out in and out of circuit for starting and stopping the instrument by means of a switch-leverj. This lever j, by means of the link j and pivoted lever jg,

carrying the guides u', is also Yused for removing the foot a4 of the plunger clearof the end ofthe bolt Il when the instrument is at rest. 4 This is necessary because the foot a4 of the plunger, if left in line with the bolt z', would limit the play of the armatures g2.

When the armatures g2 are attracted to the left in Fig. 2, the bolt ris moved to the`l'e`ft,"'

as above explained; but if the motor had stopped Working in such a position that the4 foot a4 were in line with the bolt z', then 'the bolt could not move sufciently to allowrthe armatures g2 to move into contact with the pole-pieces on the left.

The levers k and 7o" are used for raising and acts as a, guide for the paper strip cl and at the sa-me time serves as a grip to facilitate giving motion ito the levers j and 7c. The

paper strip d may be read up visually or by v means of an ordinary sounder and retransmitter.

Y Having fully described our invention, whatv We claim, and desire to secure by Letters Pata 5 1. In an instrument for receiving telegraphic messages the combination of a constantly-working plunger, a foot onsaid plunger, a punch having .a slot therein of like length` to the stroke ofthe plunger, abolt pass` ing through said punch aforked lever engagy ing and operating said bolt, and coils for oping f and. spacing currents substantiallyas erating said forked lever by the usual markherein shown'and described. V

2. In an instrument for receiving telegraphic messages, the combination of a conl The post lo? a forked lever engaging and operating saidv bolt, and coils for'operating said forked lever `bythe usual marking and spacing currents,

substantially as herein set forth.

' 4. In an instrument for receiving telegraphic messages, the combination of a constantly-working plunger, a foot'on said plunger, guides for said plunger, a pivoted lever carrying said guides, a punch, a slot insaid punch of like length to the stroke of the plunger, atension-spring attached to the punch, guides for said punch, a bolt passing through the punch,apin attached to said bolt, a forked lever to operate said bolt, and coils for operating said forked lever by the usual marking kand spacingcurrents, substantially as set `forth.

Intestimony whereof we alix our signatures in presence of two witnesses.
